Proportional Directional Valve 4WRZ32W6-360-7X/6EG24N9ETK4/D3V - Bosch Rexroth R900948665

Cylinders and hydraulic motors on presses, rolling mills or test rigs are steered in direction and speed by the 4WRZ32W6-360. The valve is pilot-operated, rated at 360 l/min nominal flow, and admits up to 1600 l/min maximum flow at 350 bar. External amplifier electronics drive the solenoids, while spool symbol W6 defines the switching function across three positions.

Benefits

• 360 l/min nominal flow in size 32, rated up to 1600 l/min maximum flow
• Operating pressure up to 350 bar on a subplate interface to ISO 4401-10-09-0-05
• Built-in pressure reducing valve plus internal pilot oil supply and return, so no separate control oil line is required
• Spool symbol W6 with three switching positions and four ports
• Concealed auxiliary actuation lets the valve be shifted during commissioning without a command signal
• FKM seals matched to HL hydraulic fluid, 43.6 kg unit weight

Application

Typical installations are press drives, rolling mills, injection moulding machines and hydraulic test rigs where large oil volumes have to be moved under control. The valve mounts on a subplate to ISO 4401-10-09-0-05 and is governed by external amplifier electronics running on 24 VDC. Internal pilot oil supply and internal pilot oil return keep the piping simple.
